In the Linux kernel, the following vulnerability has been resolved: hwmon: (w83627ehf) Fix underflows seen when writing limit attributes DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large negative number such as -9223372036854775808 is provided by the user. Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.

[REJECTED CVE] A vulnerability in the Linux kernel's hwmon subsystem (w83627ehf driver) has been identified, where writing large negative values (e.g., -9223372036854775808) to limit attributes caused an underflow due to improper ordering of operations in DIV_ROUND_CLOSEST(). An attacker with write access to these attributes could potentially trigger unexpected behavior or system instability.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
